Equivalent signals received from external systems are bolded on the foregoing waveforms (see details in
Section 2.5).
2.3 Binary inputs DI 1 – DI 4
These inputs are meant to affect operation of the system by means of external signals, for instance signals
received from other automation systems or pushbuttons. Depending on the signal voltage delivered to any
specific inputs (see Section 5.5), these inputs can be considered as two logic levels. Current status of these
inputs can be viewed on the user interface (see Section 3.1.2).
These inputs are galvanic separated from other circuits of the device, although no galvanic separation
between individual inputs is provided (see Figure 4). An input is activated when voltage of any polarity is
